PC Characteristics: Simulation FEM professional purpose

Click For Summary

Discussion Overview

The discussion revolves around the characteristics needed for a PC suitable for professional simulation work, particularly in the fields of electromagnetic and motor design. Participants explore hardware requirements for running complex simulations using software like Ansoft Maxwell, Matlab, Ansys, and COMSOL, with a focus on both performance and cost-effectiveness.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Exploratory

Main Points Raised

  • One participant suggests that the type of simulation (e.g., structural vs. fluid dynamics) significantly impacts the required computing power.
  • Another participant notes that if graphics are involved, high-end components may be necessary, which could increase costs.
  • A participant specifies the need for a PC capable of handling complex electromagnetic and motor design simulations, indicating a shift from 2D to 3D modeling.
  • One contributor emphasizes the importance of considering software recommendations for minimum hardware requirements when selecting a PC for complex modeling tasks.
  • There is a suggestion to evaluate whether to purchase a pre-configured system or build a custom machine, which could allow for future upgrades.
  • A participant warns that high-quality components, such as motherboards, can significantly affect the overall budget.

Areas of Agreement / Disagreement

Participants express varying opinions on the specific hardware requirements and the importance of graphics capabilities, indicating that there is no consensus on the optimal configuration for the intended simulations.

Contextual Notes

Participants mention various software tools and their associated hardware requirements, but there is no detailed agreement on specific configurations or budgets, leaving the discussion open-ended regarding the best approach to selecting a PC for simulation purposes.

Dear all,
I'm an electric engineer, and I usually work with software as Ansoft Maxwell, Matlab, Ansys, COMSOL...
I need a PC for serious professional simulation, and I would like if someone can give me some tips of the characteristics I should ask for this purpose.

I don't want to spend more money than the necesary, though money it's not a problem if it's needed.

I've heard about 32 GB RAM or more and Intel Xeon processor stuff, I would like to hear your opinion.

Thank's everyone!

Well, simulation of what exactly and what's the biggest, most detailed simulation you plan on?

For example, analyzing a complex structure like a bridge may take less computer power than doing a small hydrodynamic or aerodynamic simulation over a certain time period. The equations of fluid dynamics are a lot more complicated to solve than most structural equations.

It depends also on whether the simulation is entirely a mathematical project or whether you want to indulge in graphics.
If you do want graphics you'll probably want high end stuff and that doesn't come cheap.

Mainly for complex electromagnetic and motor design.

Now I'm working in 2D, but I'll need 3D soon for sure.

Maybe some graphics, though the main aim is not to do much renders.

Thanks for the quick response
 
Hello everyone,
May I add any other information, I guess that the most complex design I can ask to the computer is a Multiphysics (electromagnetic, mechanical, termical, fluids) and the typically the most complex system would be to analyse a 3D Electric motor (maybe a Interior Permanent Magnets one) in this Multiphysics (not fluids, that would be for another case).

Can anyone give me a hand?

Thanks!

If you are going to do such complicated modeling of physical systems, involving electromagnetics, fluid dynamics, or whatever, you must have looked at software to use for these analyses. Start with what recommendations this software specifies as a minimum hardware requirement for the features your next PC will have.

It's not clear if you are looking to buy a system already configured or if you want to build your own custom machine, which you can expand with more memory or a faster processor as prices come down.

You can spend more just on one insane motherboard than most people will spend on an entire system. Setting a budget for what you want to spend can also help narrow down your choices.
